I guess your point is that fixing this one transgression is the equivalent of one store implementing that rule, and if we fix more of them eventually it’s a law, making it but the first step on the journey to sustainable privacy?

It isn’t. This is recycling one bottle. It doesn’t have any sustainable long lasting effect.

To stretch the metaphor, the equivalent of one store asking for deposits would be e.g. Apple requiring full disclosure of all such tracking SDKs on the App Store page, as suggested by someone else in this thread. That’s sustainable, scalable, and that’s what might eventually even lead to legislation, as you pointed out.
